Perhaps you should try some spelling variations:
lang kyoung » wang hyoung, kang young, hwang byoung
yang yue » wang yue, yang yun, yang jui
tan yang » tan ying, tao yang, wang yang
tan yong » tan hong, tan kong, tan ying
dan yang » daun yang, wang yang, yang yang
gang hai » dang hai, shang hai, eang hay
i gang » ii gang, li gang, yi gang

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: lang kyoung yang yue ((((tan yang) OR (tan yong))) OR (dan yang)) i gang hai ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "lang kyoung yang yue ((((tan yang) OR (tan yong))) or (dan yang)) i gang hai ;~".
• Adding a wildcard symbol may retrieve word variants: lang kyoung yang yue ((((tan yang) OR (tan yong))) or (dan yang)) i gang hai ;*.
